What is the domain of the function shown in the mapping?

Mathematics
1 answer:
siniylev [52]3 years ago
3 0

Answer:

<h2>A. {x | x = –5, –3, 1, 2, 6}</h2>

Step-by-step explanation:

<em>The mapping between sets is shown in the image attached.</em>

<em />

Remember that the Input Set represents the domain, the x-values. The Output Set represents the range, the y-values.

So, basically we need to choose the set of x-values which has the same elements than the Input Set showed in the image.

Therefore, the right answer is A, because it has the same elements than the Input Set shown.

Which of these equations could represent the blue line?
belka [17]

Hello from MrBillDoesMath!


The first choice (y = 2x) is NOT the blue line because it has twice of the slope of the line y=x. That is,  for a given positive x value the graph of y= 2x  appears above the black line which is not the case for the blue line shown.

The second choice (y =.001x) is a possibility but the multiplier .001 is so small I think the graph of that line would be "close" to the x-axis. I don't think it's the blue line.

y = -x. Now here we can say NO!  That line goes through the origin all right but has a slope of -1 so is heading "downward" from left to right. That is not the blue line either.

Well, then, it seems that the last equation ( y = 1/2x) is the only remaining reasonable answer.


Regards,  MrB.

Suppose that a small country consists of four​ states:
Kamila [148]

Answer:

a.) Standard Divisor = 20000

b.) Standard Quota for State A = 66

    Standard Quota for State B = 54

    Standard Quota for State C = 26

    Standard Quota for State D = 4

Step-by-step explanation:

The country consists of four states

     A                              B                             C                     D

1,326,000                1,068,000             524,000             82,000

Total population  =  1326000 + 1068000 + 524000 + 82000

                            = 3000000

It is said that there are 150 seats in the legislature that have to be apportioned among the four states based on their respective states.

a.) Find the standard divisor

Standard Divisor = \frac{Total \hspace{0.1cm} population }{Number \hspace{0.1cm} of \hspace{0.1cm} seats}  = \frac{3000000}{150}  = 20000

b.) Each state's standard quota.

 Standard Quota for State A = \frac{1326000}{20000}  = 66.3 \approx 66

 Standard Quota for State B =  \frac{1068000}{20000}  = 53.4 \approx 54

Standard Quota for State C  = \frac{524000}{20000} = 26.2 \approx 26

Standard Quota for State D  = \frac{82000}{20000}  = 4.1 \approx 4

    If the quota are rounded to the nearest number and added then we find that the total is 149 and we so we take the quota which has the highest decimal part and round up and then summing all the quotas we get a total of 150 seats.

How to transfer a decimal to a fraction or mixed number?
klemol [59]
A decimal that is like .11 the amount of #s in the decimal is 2 so it'll mean 2 0s like that would be 11/100. So if it was .209 it would be 209/1000.

Solve for x <br><img src="https://tex.z-dn.net/?f=4x%20-%2016%20%3D%200" id="TexFormula1" title="4x - 16 = 0" alt="4x - 16 = 0"
Shkiper50 [21]
Get x by itself
add 16 to both sides, so 4x = 16
divide both side by 4 and x =4
